Explanation:

Answer:

Along boundaries plates are brittle and the crust fractures (breaks and cracks) forming Faults

Explanation:

Brittle material are substances that looks hard but can be easily broken by strain. Brittle deformation leads to crack and fracture of the material involve. Brittle crust lacks elastic ability , elasticity in this rocks are almost absent.

Fractures and cracks in rocks form fault. Fault is a discontinuity in rocks with an appreciable displacement. Fault is a displacement in rocks relative to one part. Generally, Fault occur when brittle rock fracture or crack, the fractured rocks move relative to one another.

Differential stress can cause rocks to fracture. If that part of the crust lacks ductility the stress on the rock will cause a brittle deformation. The brittle deformation causes fracture(breaks and cracks) leading to structure like Faults and Joints.    

Mercury's surface has many craters because it has no atmosphere to protect it from meteoroids or comets.

Mercury's surface is riddled with craters, owing to the lack of a strong atmosphere to shield it from meteoroids and comets.

Meteoroids are small rocky or metallic objects in space that range in size from minuscule particles to bigger things with diameters of several metres.

They are generally relics of the solar system's early creation or debris expelled by asteroids or comets.

Unlike Earth, which has an atmosphere that burns up or deflects most smaller things that enter it, Mercury's thin atmosphere offers little to no protection.

Thus, meteoroids and comets can collide with its surface, causing countless craters to form over time.

Answer:

Explanation:

You are expected to have some understanding of how these devices work. It is helpful to actually see one or take it apart.

Magnetic force is involved where there is a magnet or material that responds to a magnet.

Of course a compass aligns itself with the magnetic field of the earth.

A magnetic door catch uses a magnet or pair of magnets to attract a metal plate, holding the door closed.

A speaker uses the reaction between the magnetic field in a coil of wire and that of a fixed magnet to move the speaker cone. (There are versions of speakers that use electrostatic force (electric field), but those are less common.)

A motor moves by creating a magnetic field in the armature that reacts with one in the stator. The latter can be created by fixed magnets, or by an electric current.

__

Electric force is involved when the operation is a result of the attraction between oppositely charged particles.

An electronic air filter uses the attraction of charged particles to attract "dirt" in the air to a charged surface, so removing it from the air.

Socks from the dryer often cling to each other (static cling) because the charge they get from rubbing other dryer contents is not dissipated in the dry air. (Fabric softener can reduce this effect, presumably by making the materials more electrically conductive.)

Answer:

See the explanation below

Explanation:

Ohm law is defined as the voltage is equal to the current product by the resistance.

V = I * R

where:

V = voltage [volt]

I = current [amp]

R = resistance [ohm]

Therefore for a current to exist there must be a voltage and elements that exert resistance to the passage of electrons from one point to another.

There must be a closed loop between the connection points of the source, so that the current can flow freely. Any opening of the circuit will interrupt the current flow.

Answer:16ohm

Explanation:

Potential difference(v)=24volts

Current(I)=1.5amperes

Resistance(r)=?

r=v/I

r=24/1.5

r=16ohms

Final answer:

To calculate the resistance of an electrical appliance using Ohm's Law, divide the voltage by the current. With a 24-volt source and a draw of 1.5 amperes, the appliance's resistance is 16 ohms.

Explanation:

To find the resistance of an electrical appliance, we can use Ohm's Law, which states that resistance equals voltage divided by current (R = V/I). Given that the appliance draws 1.5 amperes of current from a 24-volt source, we can calculate the resistance as follows:

R = V / I
R = 24 V / 1.5 A
R = 16 ohms

Therefore, the resistance of the appliance is 16 ohms.

The MOST likely location of the LEAST concentration of mass in an atom is at point D, which is at the radius of the atom.

1. The nucleus of an atom contains the majority of the mass and is located at the center of the atom.

2. As you move away from the nucleus towards the electron cloud, the concentration of mass decreases significantly.

3. At the radius of the atom (point D), the mass is distributed over a larger area, leading to the least concentration of mass at this point.

4. Therefore, point D, being at the outer edge of the atom, is the most likely location of the least concentration of mass in an atom.

This concept is crucial in understanding the distribution of mass within an atom and how it varies based on distance from the nucleus.

Answer:A loudspeaker produces a musical sound by means of the oscillation of a diaphragm. The loudness of sound produced depends upon Amplitude of vibration.

Explanation:

The loudness of a sound depends upon the amplitude of vibrations. A sound will be louder if the amplitude of vibration is greater but if it is smaller than sound will not be louder.

Now it is the vibration of a sound that determines it's amplitude. Amplitude signifies the maximum distance moved. It means the extent of vibration If is vibrations have more amplitude than sound will be louder but if the amplitude of vibrations is shorter than the sound will be softer.

The loudness of sound produced depend on the frequency of oscillation, the amplitude of oscillation, the kinetic energy of oscillation

Explanation:

Loudness of an instrument is proportional to its amplitude

The  amplitude ,frequency of the sound wave will be a function of both the speed and the amplitude of the cone.( i.e. keep the amplitude constant and vary the kinetic energy of the oscillation of the speaker cone and the frequency will change. )

If you step slowly into a pool, the ripples you make are reasonably small, whereas if you take a running jump (i.e. high kinetic energy).

Answer:

Explanation:

An air mass is a large body of air that exhibits uniform temperature and moisture characteristics and helps to determine the weather within an area. Warm air masses tend to form over oceans in warm-temperature regions of the tropics and sub-tropics, while cold air masses tend to form over land in cold-weather regions nearer the poles. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles. These air masses can undergo gradual, but significant, changes as they pass over warmer or colder land surfaces encountering different types of air. These boundary lines are called fronts.

Cold fronts occur when a cold air mass moves into warmer air. Since cold air is heavier than warm air, the incoming colder air forms a wedge that displaces the warm, and often moist, air at the surface. As the warm moist air rises, towering clouds often form releasing energy in the form of brief, intense rain storms with high winds and lightning. On the other hand, warm fronts will ride up and over cold air near the surface. These fronts can also cause clouds and rain, but they tend to be less violent and longer lasting.

Air pressure is determined by how much the air weighs in a given space. Pressure varies with altitude, with denser air residing in lower altitudes and lighter air in higher altitudes. This is caused by the Earth’s gravity—its strength decreases the farther away from the center of the planet, therefore it holds fewer molecules together in the same amount of space. Air pressure is also a function of temperature and density; differences in pressure can be an important weather maker. As air descends, it warms, inhibiting cloud formation which is often associated with good weather. Air rises in areas where the pressure at the surface is low. As it rises, the air cools and the humidity condenses to form clouds and precipitation. The centers of all storms are areas of low pressure; therefore, low pressure is often associated with bad weather.

Erosion is the removal of weathered materials from the surface of earth. It is one of the processes that sculpts the surface of the earth due to its unique earth moving capabilities.

The main agents that contribute to erosion include water, wind, ice(glaciers), and gravity. They each shape the earth's landscape in distinct ways such as through water erosion, wind erosion, glacial erosion, and erosion caused by gravity.

There are several agents that significantly contribute to erosion, a common geologic process. The main agents of erosion include water, wind, ice(glaciers), and gravity. Water erosion occurs when moving water such as rain, rivers, or ocean waves wear down the earth's surface. Wind erosion happens especially in dry, bare areas where loose soil can be easily picked up by the wind. A glacier's movement can erode the land through a process called glacial erosion. Lastly, gravity contributes to erosion through landslides and rockfalls, where rocks and soil are pulled down by gravity. Each of these agents shape the earth's landscape in different ways.

Answer:

It is exerted in all directions at sea level, and this is because air molecules move in all directions.

At sea level, air pressure exerts force in all directions.

At sea level, air pressure exerts force in all directions. This force, known as atmospheric pressure, is the result of the weight of the air molecules above a given point.

Since air is a fluid, the air pressure at any location is distributed evenly in all directions, including upward, downward, and sideways.

This balanced distribution of air pressure is what helps maintain the stability of the Earth's atmosphere and is an essential factor in various weather phenomena and atmospheric dynamics.

There are three kinds of heat transfer: conduction, convection, and radiation.

Conduction is the heat transfer by direct contact of a hot object with a cold object. It is transmitted by the vibration of the particles and not by translation motion. That is not what it is shown: the clouds are not in direct contact with the ground.

Heat transfer by convection is result of the motion of the particles in fluis, like water or air: particles move from hotter regions where they have high kinetic energy to colder regions where the particles have lower kinetic energy. Since the hotter fluids have lower density than the colder fluids, there will be a continous movement of parciles and heat. That is what is shown in the figure with the arrows.

Radiation heat transfer mechanism always occur but is only important when the temperature of the hot object is really high, like in a fire, or in a resistance to red hot, or in the Sun. The heat is radiated by infrarred radiation. That is not what is shown in the figure.

Answer:

Mass is considered as positive as it is the amount of matter and as nothing weighs less than zero. But the concept of charge in electricity can be both positive and negative because of the behaviour Observed in electrical phenomena , Conservation of charge , Interaction of charged objects and Atomic and subatomic structure

Explanation:

Understanding the nature of mass and its positivity

Mass is the amount of matter in an object. As the amount of matter cannot be less than zero. It is always greater than or equal to zero.

Exploring the concept of electric charge
Incase of electric charge it acts differently as per the system it belongs to, The following are some observation which substantiate the presence of negativity and positivity of electric charge.

a) Observations of electrical phenomena: People have observed electrical effects, such as static electricity, where objects can be attracted or repelled without physical contact. This led to the idea that there are two types of charges involved.

b) Conservation of charge: Scientists observed that charge is conserved in interactions. For example, during various experiments involving the charging and discharging of objects, the total amount of charge in a closed system remained constant. This observation supports the idea of positive and negative charges.

c) Behavior of charged objects: Through experiments, scientists found that like charges repel each other, while opposite charges attract. This behavior is consistent with the existence of positive and negative charges.

d) Atomic and subatomic structure: Detailed studies of atoms revealed that they consist of positively charged protons, negatively charged electrons, and neutral neutrons. The balance between protons and electrons determines the overall charge of an object.

Hence the mass never considered as negative and we think differently for electric charge

Answer:

Initial angular position of the disc is 3 radian

Explanation:

As we know that the angular acceleration of the disc is given as

[tex]\alpha = 0.50 rad/s^2[/tex]

initial angular speed is given as

[tex]\omega = 1 rad/s[/tex]

now we know that angular displacement of the disc is given as

[tex]\theta = \omega t + \frac{1}{2}\alpha t^2[/tex]

[tex]\theta = 1(2) + \frac{1}{2}(0.5)(2^2)[/tex]

[tex]\theta = 3 rad[/tex]

now we have

[tex]\theta_f - \theta_i = 3 rad[/tex]

[tex]6 rad - \theta_i = 3[/tex]

[tex]\theta_i = 3 ard[/tex]

Final answer:

To find the initial angular position of the disk, we used the kinematic equation for rotational motion and the given values (angular acceleration, initial angular velocity, and final angle) to calculate that the disk's angular position when the acceleration started was 3.0 rad.

Explanation:

The problem is asking us to find the angular position of the disk when it started accelerating. Since we know the angular acceleration, the initial angular velocity, and the final angular position, we can use the kinematic equations for rotational motion to determine the initial angular position.

The kinematic equation we'll use is:
[tex]\( \theta = \theta_0 + \omega_0t + \frac{1}{2}at^2 \)[/tex],
where [tex]\(\theta\)[/tex] is the final angular position,[tex]\(\theta_0\)[/tex] is the initial angular position, [tex]\(\omega_0\)[/tex] is the initial angular velocity, [tex]\(a\)[/tex] is the angular acceleration, and [tex]\(t\)[/tex] is the time.

Given:
[tex]\(\theta = 6.0 \text{ rad} \)[/tex] (final angular position),
[tex]\(\omega_0 = 1.0 \text{ rad/s} \)[/tex] (initial angular velocity),
[tex]\(a = 0.50 \text{ rad/s}^2 \)[/tex] (angular acceleration), and
[tex]\(t = 2 \text{ s} \)[/tex] (time).
We rearrange the equation to solve for [tex]\(\theta_0\)[/tex]:
[tex]\(\theta_0 = \theta - \omega_0t - \frac{1}{2}at^2 \)[/tex]

Plugging in the values:
[tex]\(\theta_0 = 6.0 \text{ rad} - (1.0 \text{ rad/s} \cdot 2 \text{ s}) - \frac{1}{2} \cdot 0.50 \text{ rad/s}^2 \cdot (2 \text{ s})^2 \)[/tex]
[tex]\(\theta_0 = 6.0 \text{ rad} - 2.0 \text{ rad} - 0.50 \cdot 2 \text{ rad} \)[/tex]
[tex]\(\theta_0 = 6.0 \text{ rad} - 2.0 \text{ rad} - 1.0 \text{ rad} \)[/tex]
[tex]\(\theta_0 = 3.0 \text{ rad} \)[/tex]
So the disk's angular position when the acceleration started was 3.0 rad.

Explanation:

The work done on the barbell is -165.62 Nm.

Explanation:

Work done on any object is the measure of force required to move that object from one position to another. So it is determined by the product of force acting on the object with the displacement of the object.

In the present problem, the displacement of the object on acting of force is given as 1.3 m. And the weight of the object which is a barbel is given as 13 kg. As the work is to lift the object from the ground, so the acceleration due to gravity will be acting on the object. In other words, the force applied on the object to lift it should be in opposite direction to the acting of acceleration due to gravity.

Thus, [tex]Force = - Mass * Acceleration due to gravity = - 13 * 9.8 =-127.4 N[/tex]

Now, the force is -127.4 N and the displacement is 1.3 m.

So, [tex]Work done = F*d[/tex]

[tex]Work done = -127.4* 1.3 = -165.62 Nm[/tex]

So, the work done on the barbell is -165.62 Nm.
